A water filtration system with magnetite has a more aggressive backwash in the cleaning phase, as well as the ability to recover the magnetite by using a magnet. It is also used in coal mining operations as a slurry with water to remove the heavier impurities by allowing the less dense coal to float to the surface.

Hematite: A primary ore of iron and a pigment mineral

Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

Global Drivers for High Grade Concentrate | Magnetite Mines

Over the last decade, there has been structural shift in the global iron ore markets favouring higher-grade, lower-impurity iron ore products. Generally, the lower the Fe grade of the iron-based feedstock, the higher the level of impurities such as phosphorus, silica, sulphur and alumina.

Magnetite Recovery in Coal Washing by High Gradient ...

Fine magnetite mixed into a water suspension is commonly used in coal preparation to create a pseudo- specific gravity great enough to effect separations between coal and associ- ated impurities. The magnetite must not only be reclaimed but must also be cleaned to prevent coal and impurities from building up in the washing cir- cuit.

Influence of High Conductive Magnetite Impurity on the ...

The electrical conductivity of dry sintered olivine aggregates with various contents of magnetite (0, 3, 5, 7, 10, 20, and 100 vol. %) was measured at temperatures of 873–1273 K and a pressure of 2.0 GPa within a frequency range of 0.1–106 Hz. The changes of the electrical conductivity of the samples with temperature followed an Arrhenius relation.

Hematite - Wikipedia

Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While the forms of hematite vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle. Maghemite is a hematite- and magnetite-related oxide mineral.

The Extraction of Iron - Chemistry LibreTexts

Impurities in the iron from the Blast Furnace include carbon, sulfur, phosphorus and silicon. These have to be removed. Removal of sulfur: Sulfur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulfide.

Iron Ore - AIMR 2011 - Australian Mines Atlas

Australia's iron ore reserves and resources are in both hematite and magnetite ores. Because of the high average grades (% Fe) of hematite ores when compared to the average grades for magnetite ores, it is necessary to report national resources in terms of contained iron.

Properties of magnetite nanoparticles synthesized through ...

Also, the role played by impurity phase should not be ignored since it reduces the magnetic component in the sample. Magnetite (Fe3O4) is a ferrimagnetic iron oxide having cubic inverse spinel structure with oxygen anions forming a fcc closed packing and iron (cations) located at the interstitial tetrahedral sites and octahedral sites.

Influence of High Conductive Magnetite Impurity on the ...

Magnetite is a mineral and one of three common naturally-occurring oxides of iron. Its chemical formula is Fe 3 O 4 and it is a member of the spinel group. Magnetite is ferrimagnetic, it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth

Iron Production - Chemistry LibreTexts

Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron.
